A yellow SVG face is constructed from D3.js v5 shapes, including a circle, eyes, eyebrows, and a mouth path. The code uses `d3.select`, `d3.arc`, and SVG groups to position each feature relative to the center. Eyebrow rectangles animate upward and back via chained `transition().duration(2000)` calls. The example demonstrates modular group-based layout and smooth transition sequences in a React-friendly, plain SVG rendering context.
